TS文件无法转换成MP4格式

Question

我从直播流的m3u8中下载下来的TS文件片段，在直播结束之后，使用ffmpeg合成整个文件时

ffmpeg  -f concat -safe 0 -i 1.txt -c copy 1.mp4

无法进行合成。提示如下错误：

后来我使用格式工厂，查看TS文件的属性，发现现在的TS文件中Video属性是这样的

Video
ID                                       : 256 (0x100)
Menu ID                                  : 1 (0x1)
Format                                   : HEVC

Bit depth                                : 8 bits

而上述异常的TS文件中Video属性却少很多，没有Color space，Width，Height 等属性值。

Video

有没有办法把这些属性直播添加到TS文件中呢？
